The '''CSRLIN''' function returns the current text row position of the [[PRINT]] cursor.

{{PageDescription}}
|
||
|
* The value returned is within the range of 1 to the current number of rows in the [[SCREEN]] mode used.
|
||
|
* In screen modes that support page flipping, the [[CSRLIN]] function returns the vertical coordinate of the cursor on the active page.
|
||
|
* x = [[POS]](0) returns the column location of the cursor.
|
||
|
|
||
|
|
||
|
''Example:'' A semicolon stops the print cursor immediately after the print.

:''Explanation:'' "HELLO " is printed and the semicolon stops the cursor immediately after the text. The '''CSRLIN''' variable records the current print cursor's text row in Y. The [[POS]] function records the current print cursor's text column in X. The second [[PRINT]] statement displays the comment "WORLD" on the 10th line of the screen. The last [[LOCATE]] statement restores the position of the cursor to the original line and column immediately after the first print.
